But that spaghetti isn’t the only noodle-like thing your dog is going to vomit, he may actually be giving out roundworms. Roundworms look much like spaghetti and are a common infestation in dogs due to poor hygiene, they look so much like spaghetti that you might be questioning yourself, “Did I feed my dog noodle soup? Why is my dog throwing up spaghetti?”

Once upon inspection, I was surprised to notice white long worms wiggling in the vomit. It more clearly looked as if the dog was throwing up spaghetti when in reality he never had spaghetti.

If your dog had noodle soup and threw it up, that’s nothing indifferent from the viral video where the dog throws up spaghetti. But if he was not fed anything as such, and was closely supervised, what are those wiggly, long noodles doing in there?

When I took the matter forward to my veterinarian, I found out my poor puppy had been holding worms in his gut for a long time. WORMS IN THE STOMACH? Yes, totally live worms living and reproducing inside your dog.

These worms greatly resemble spaghetti in shape and consistency as being long, slippery, and wiggly. You can say the spaghetti strands are 5-8cm long, usually white or light brown in color. At first sight, you can absolutely fool yourself for spaghetti rather than roundworms!

Since puppies have a weak immune system they are more susceptible to getting worm infestation. This is the reason puppies are dewormed every two weeks until they’re 12 weeks of age. After that, the pattern is to be followed every 6 months till the time he turns 3 years old. However, Roundworms are still the most common worms found in dogs.

Why is my dog throwing up spaghetti?

Every time my dog pukes, as a good dog mom, I make sure to analyze (just by looking) if the furry boy has been intaking something hazardous. It wouldn’t be shocking news if I say from small toys to small plastic pieces, I found the least expected items in my dog’s vomit.

Dog’s most commonly get roundworms when they get in contact with eggs in other dog’s poop. The eggs grow up in the intestine and then migrate upwards to the lungs. They may be coughed up and swallowed and later given out in the vomit. This happens rarely, but if it does it’s time to rush to a vet!

What are the other routes of getting the parasite?

Dogs may also get worms by eating animals that have worms like mice or rabbits. On the other side, soil contaminated with roundworms can also be a source. A dog mother can pass on the parasite during birth and even through her milk. Moreover, it is known that the dormant larvae in a mother’s intestine can become active during pregnancy that increases the risk of infestation in puppies.

Worms can also be transferred to other human family members, especially kids who do not take precautions with sick dogs. So deworming is pretty essential to keep everyone around the house healthy.
